Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed June 5, 1905. Serial lilo. 253,811.

To all whom it 77mg! concern:

v Be it known that 1, JOHN Fosrnn, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have hivented certain new and useful ln'iprovements in Stanohions; and T dodethe following to be a full,

on as will enable others skilled in the art to wh ch it appertains to make and use the same.

My invention relates to improvements in cattle-stanchions and it consists in the novel construction, combination, and arrangement of devices herein shown and described.

' One object of the invention is to provide device oi this character which 1s of simple construction, comparatively 1nexpensive of 1 production, durable in use, and eflicient in operation.

Another object of the invention is to pro- 'vide a stanchion which is light. and strong and comfortable for the animal confined therein.

The above and other objects, which will appear as the nature of the invention is better understood, are accomplished by the con- 'struction illustrated in the accompanying drawings, in which Figure 1 is a front view of a stanchion, showing it in its closed position in full lines and in its open position in dotted lines. Fig. 2 is a side elevation of the stanchion. Fig. 3 is a detail sectional view, on an enlarged scale, of the head of the stanchion, showing the locking-latch for the swinging side member or bar; and Fig. 4 is a detail sectional view taken on the line 4 4 in Fig. 3.

, Referring to the drawings by numeral, 1

denotes my improved stanchion, which comprises two side members or bars 2 3, a conneoting bottom member or base 4, and a top 2 member or head 5.

The upright bars or members 2 3 are preferably formed of hollow steel tubing, and the base 4 and head 5 are preferably in the form of castings; The side nie'mber or bar 3 is riveted or otherwise fastened in a tubular socket 9, formed at one end of the base 4, and at the opposite end of the latter is formed a slotted or recessed portion 10, in which is pivoted the lower'end of the side member or bar 2. This pivotal connection is eil'ected by riveting" or otherwise fastening in the lower end of the tube 2 a plug having a tongue 11, which is adapted to project into the recess or bifurcated portion 100i the base 4 and to receive the pivot bolt ber or bar 0 i or screw 2.

The upper end of the said memrivetcd or otherwise fastened in a tubular socket 13, formed at one end of the head 5. T he upper free end of the swinging member or bar 2 is adapted to be fastened to the opposite end of the head 5 by a latch device i l, which. co a hook-shaped member 15 up .s end of the bar 2, a guide member lo med at one end of the head 5, a1. latch 17, pivoted upon said head. ber .15 is in the form of a curved hool: formed upon a plug 18, which is riveted or otherwise fastened in the upper end of the tube 2. The guide member 16 of the latch device comprises a slot or recess 19, formed in one end of the head 5, and oppo- -sitely-disposed grooves 20, formed in the .walls oi the slot or recess 19 and adapted to receive lateral projections 21 upon the opposite sides of the inner portion of the hook 15, as clearly shown in Figs. 3 and 4 of the drawings. The slot 19 and grooves 20 guide the hook beneath the upwardly-curved outer end 22 of the latch 17, so that said end of the hook will enter a slot or opening 23, formed in said end of the latch. The latch 17 is pivoted, as shown at 24, centrally in a longitudinal slot 6, formed in the head 5, and has a projecting finger-piece 25 at one of its ends to permit it to be readily operated. The latch or latchlever 17 has its slotted end held normally in engagement with the head 5 by a coil-spring- 26', which has one of its ends secured to a lug upon said latch and its other end to a rivet or pin 27, located in the slot 6 in said head 5.

The stanchion is adapted to be supported in a vertical. position by suitable chains or other flexible connections 28, provided at its top and bottom, and the opening movement of the swinging side member or bar 2 is adapted to be limited by a chain 29, which has one of its ends secured to the free end of the latter and its opposite end to the head 5 or to the upper chain 28. The use of the chain 29 renders the device more convenient to handle and prevents injury to the hinge at the lower end of said swinging member.

The construction, operation, and advantages of the invention will be readily under stood from the foregoing description, taken in connection with theaccompanying drawings. It will be seen that by swinging the bar or member 2 from its dotted-line position (shown in Fig. 1) to its full position, after the animals head has been placed between the side bars, the curved upper end of the hook 15 will elevate the latch 17 until the hook enters the slot 23 in said latch, where upon the spring 26 will return the latch to lock the bar 2 in its closed position. By depressing the finger-piece 25 of the latch its slotted end may be readily disengaged from the hook 15, so that the member 2 may be swung outwardly to' its opened position.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

What I claim is 1. A stanchion com rising a pair of bars, one of which isadapte to swing, a hook upon said swingingv bar, jlateral projections adjacent to said hook, a head upon the other of said bars and formed with a recess to receive said hook and with grooves to the walls of said recess to receive said rojections and a swingin latch upon said liead and formed with a slot to receive said hook, substantially as described.

2. A stanchion comprising a tubular side said slotted head to limit the opening move" ment of said swinging member, and a chain for suspending said stanchion, substantially members and having a tongue adapted to be pivoted in the recess or bifurcated end of said base, a head having a socket member at one end adapted to receive the upper end of one of said side members and formed at its oppo site end with a guide to receive theupper end of the other of said side members, said guide comprising a slot or recess 'formed with grooves in its walls, a hook upon the upper end of the pivoted side member adapted to enter the slot of said guide, lugs upon said hook to enter the grooves of said guide, a

latch fivoted in a slot in said head and forms with an upturned slotted end adapted to engage said hook, a finger-piece upon said latch, a spring for holding said latch normally in engagement with said hook, and a chain. or other flexible connection for limiting the swinging movement of said pivoted side member.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
